数组连接与字符串连接

哪种方法更快？

阵列连接：

var str_to_split = "a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z"; var myarray = str_to_split.split(",");

var output=myarray.join(""); 字符串连音：

var str_to_split = "a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z"; var myarray = str_to_split.split(",");

var output = ""; for (var i = 0, len = myarray.length; i<len; i++){ output += myarray[i]; } 问题来源于stack overflow
